it has been recognized that acute and chronic stress has an impact on the immune system. acute stress may have a stimulating effect on the immune system, while in the case of chronic stress specially depression, the immune system could be down-regulated. however, an association between depression and a higher number of circulating white blood cells with increased activity has been reported. ele...

Background: Cancer is a public health emergency. It has a high mortality rate despite numerous studies on pharmaceutical therapies. Chimeric antigen receptor-natural killer (CAR-NK) cells are promising immunotherapy that could be used to treat cancer, especially leukemia. However, the evidence is still unclear. Thus, this systematic review aims to summarize the evidence regarding the use of CAR...

Abstract Background: Cure rates for osteosarcoma (OS) have not improved in >30 years and no new effectivetherapies been identified metastatic disease. Natural killer (NK) cells become an attractive tool cancer immunotherapy. Efficay is by direct tumor targeting introducing a specific chimeric antigen receptor (CAR). Emerging knowledge suggests CD70 to be viable candidate as expression hi...

Introduction. Currently, more and attention is being paid to possible strategies for preventing the development of graft-versus-host disease (GVHD) reducing risk infections while maintaining antitumor effect — graft-versus-leukemia (GVL). In this context, study natural killer cells (NK-cells) seems be quite promising. Aim – analyze biological functional properties NK-cells after allo-HSCT, thei...

روش های مانده ای دسته ای از روش های تکراری می باشند که جهت حل سیستم های خطی با ماتریس ضرایب تنک و بزرگ بکار می روند. نوعی از این روش مشهور به روش gmres از اهمیت فراوانی برخوردار است. در این پایان نامه روش مانده ای جدیدی تحت عنوان minres-nk را بر روی دسته ای از دستگاه های معادلات خطی با ماتریس ضرایب نرمال وقتی که طیف ماتریس روی یک منحنی درجه k قرار دارد بیان نموده و آن را با روش gmres مقایسه می ...

Background and Objectives: Tumor-infiltrating regulatory T (TI-Treg) cells perform the significant function in cancer immune escape. In this study, the third generation CAR construct was designed against human CD25 antigen, the significant cell surface biomarker of TI-Tregs. Methods: Initially, the construct of anti-CD25 CAR was designed. Using RNAfold web server, the RNA secondary structure wa...

ABSTRACT Natural Killer cells (NKs), are considered an important first line of defence and were originally defined by their ability to kill certain tumor cells and virally infected cells. Our aim is to study expression of HLA class-Ia on tumor cell lines and their susceptibility of NK cells. In this study MDA-MB-468 tumor cell line (NCB1, C208) That derived from human breast adenocarcino...
